Request for understanding
I must ask this question for some understanding. If the process for 8GB stick creation merely uses "xz" utility for getting to the bootable full-install on USB, WHY do I need to have any system that has "f2fs"? Reason: "xz" decompression step uses "dd" comannd-type approach to stream the datablocks needed to the USB.-in fact, the process to create the full-install doesn't care what's on the USB stick when it is run. "xz" is going to over-write whatever exist in the first 8GB on that USB.

Code:

xz --decompress --stdout quirky-6.1-8gb.img.xz > /dev/sdb

Currently, I trying to understand the need for Precise 5.7.1 to get to the running full-install on the USB stick using "xz".

Help if you can shed some light on this._________________Get ACTIVE Create Circles; Do those good things which benefit people's needs!

In this case you are using "Method D: 8GB image"

You don't when installing by "Method D"

Code:

xz --decompress --stdout quirky-6.1-8gb.img.xz > /dev/sdb

This command unsquashes the image

"quirky-6.1-8gb.img"

before writing it to the flash-drive. It contains a partition with f2fs-filesystem.

... or any distribution having the 'f2fs-tools'.

You only need 'f2fs-tools', when using

"Method A: install to any size Flash drive"

where 'mkfs.f2fs' is needed to make a partition with f2fs-filesystem. Please look into the install-script for "Method A":

Thanks @Cinclus_Cinclus. You re-enforce the case I wrote about. The post describing those cases could be worded a little more accurately. But, I think, by now, most have gotten the message we share with better clarity.

What I had found is that any system that has "xz" support correctly writes the USB for booting in this distro's case. There was no requirement for f2fs as it only confused things in understanding where that specific case/command was used to generate the USB.

Thanks again for pointing this out._________________Get ACTIVE Create Circles; Do those good things which benefit people's needs!

just moved a flash drive install to a different machine. quirky tahr 6.5 (four?) connected, booted, did everything well in its new location. new machine had what i thought were hard drive issues, but it's grinding and grumbling with it removed so i guess it's a fan issue or some other moving part...think that's the last remaining one though. anyway, i remember this being a question at some earlier time and, yes, you can move a usb installation of quirky tahr from computer to computer. (in this case, a dell and an asus netbook) and have it go smoothly. all my autostart/automount stuff went correctly, it synced with drop box after having been on a shelf for a couple of weeks...

just moved a flash drive install to a different machine. ... it [went] smoothly...
very nice.

I agree, moving a flash drive install from PC to PC goes smoothly with QT 6.0.5. It's one of the reasons I like it; using the same configuration on all PCs. I moved the same usb key from/to a dell notebook, two acer notebooks, two hp notebooks, a samsung netbook and even a couple of old desktops. Had zero issues so far.
